ID:186065 Can't place fast PLL "<name>" in PLL location <name> because too few differential I/O node locations available

CAUSE: The Fitter cannot place the specified fast PLL in the specified location because there are not enough available locations for the differential I/O nodes driven by the fast PLL.

ACTION: Change the location assignment for the fast PLL or its differential I/O nodes, or modify the design to reduce the number of differential I/O nodes driven by the fast PLL.
